Parameter Comparison

Engineering Selection Recommendations

Both the RN55E2001CRSL and RN55E2001BB14 are active products from Vishay Dale within the military-grade RN55 series. The primary distinction is packaging format and tolerance specification. The RN55E2001BB14 provides tighter tolerance (±0.1% versus ±0.25%), making it suitable for applications requiring higher precision. Both components maintain identical electrical and thermal characteristics, military compliance, and physical dimensions. Selection between these parts should be based on tolerance requirements for the specific circuit application and packaging format availability (Tape & Reel versus Bulk).

Frequently Asked Questions (FAQ)

Q: Can RN55E2001BB14 directly replace RN55E2001CRSL in existing designs?

A: Yes. Both components share identical resistance value, power rating, package type, temperature range, and physical dimensions. The RN55E2001BB14 offers improved tolerance specification (±0.1% versus ±0.25%), which is a performance enhancement rather than a limitation. Circuits designed for the RN55E2001CRSL will function with the RN55E2001BB14 without modification.

Q: What is the significance of the tolerance difference?

A: Tolerance defines the acceptable deviation from the nominal 2 kOhms resistance value. The RN55E2001CRSL allows ±0.25% deviation (±5 ohms), while RN55E2001BB14 allows ±0.1% deviation (±2 ohms). Applications requiring tighter resistance accuracy benefit from the RN55E2001BB14 specification.

Q: Are there packaging considerations when substituting these parts?

A: Yes. The RN55E2001CRSL is supplied in Tape & Reel (TR) format, while RN55E2001BB14 is supplied in Bulk format. Tape & Reel packaging is optimized for automated assembly processes, whereas Bulk packaging is suitable for manual assembly or smaller production volumes. Verify that your assembly process accommodates the available packaging format.

Q: Do both parts meet military specifications?

A: Yes. Both components are part of the military-grade RN55 series and comply with MIL-R-10509/7 specifications. Both feature flame retardant coating, moisture resistance, and safety-rated construction.

Q: What is the impact of RoHS and REACH compliance status?

A: Both components are RoHS non-compliant and REACH Affected. This status is consistent across the RN55 military series. Verify compliance requirements for your specific application or regulatory jurisdiction before final component selection.
